Ancient pottery and porcelain is the child of a times, it is that times raw material choice, treatment and figuration craft, apply glair and outfit to burn method of method, adornment and ability law, and the objective report of all elements such as the use requirement of people and aesthetic hobby.
In be collected at ordinary times, how will identify past dynasties and current tall copy porcelain? Do its want a dot where to? Below only from " old flavour " the experience that will talk about the author.
Before telling the following, must reiterate, appraisal of ancient pottery and porcelain is a professional skill that needs to have rich practice to add rich theory. Common saying says: Have no the person that academic practice is not provided and weigh appraisal.
Old flavour natural, it is us the first feeling to appraisal object -- old mannish.
It is be handed down from ancient times no matter taste or come up out of land content, because passed the small acid, alkaline natural decency in Kuang Yue's abiding air, people is being used, when appreciation touch for a long time, knock against, bring about glaze not to have dazzling float light (dry is smooth) , below strong light glaze does not have the high spot of dazzling, to the person a kind of shining and downy, lukewarm embellish is like the feeling of jade.
Be handed down from ancient times is tasted in using a process, glaze can appear natural, irregular, relatively the cut mark that all points and had used old mark, if encircle sufficient Duan Guang to slip, call somewhat " bag oar " fat feeling. Those who come up out of land is much leave rust having land, be in the place that show a fetus to be able to smell an earthy odour more.
Gao Fang tastes what should make to have old taste, only method is to do old. The burnish with dazzling face of take out new enamel, cannot leave to be opposite with acid and alkali of glaze corrode, go can making glaze not smooth, hazy solely with this law, feel character without jade, when be being touched with the hand acerbity and sluggish; Dagger is formed in bringing up old porcelain to use a process with the method of a variety of burnish, this kind of factitious cut mark often distributings inhomogenous, some bruise are too deep, overweight, some shows striation of parallel form gall (if pursue) .
Copy tastes factitious nick
Factitious ground is done in implements surface with all sorts of methods " earth becomes rusty " , but with tasting natural earth to become rusty really is different. The true rust that taste earth is long-term dip buries implements in soil, it is a kind of deposit in implements apparently hoar " earth is alkaline " be caused by. Color of true earth rust is inhomogenous, the depth that has barge of full of stains or spots refute changes, dry like child unwashed diaper catchs the trace on. True earth rust can scrape with bit, blow below submit hoar powder form, and glaze does not suffer destroy. Do old all sorts of marks that leave, in times taller (40~100 times) the observation below magnifier all feels factitious.
Below a variety of phenomena, it is to make the mark that makes old or intentionally in fire process likely very, it is the common phenomenon that current copy tastes:
1, glaze is lacklustre, have acerbity, alkaline cankerous hazy feeling;
2, when the hand feels glaze not smooth, have acerbity and the block hand feeling of sluggish;
3, bright into the product after changing sufficient end embryo is dry, have factitious burnish, stain, do not have nature " bag oar " fat feeling (graph 2) ;
4, sufficient end mud and glair have sex place have flint of a gleam of red, it is to use a kind of lubricious mud to besmear after going up, be burned those who go out, shape of the hull that show a skin (graph 3) ;
Copy tastes factitious flint red
5, on implements mouth edge and edge of crock mouth mouth pare glair is much and factitious, labour strikes someone broken factitious phenomenon (graph 4) ;
Copy is tasted pare artificially glair
6, glaze has parallel, deeper cut mark, distributing inhomogenous, the local cut mark that comes up against not easily is much instead;
